Is there any software to watch ZMD DD SBN8 from Windows Phone?
I didn't find any dedicated applications released by the ones who manufactured the DVR's but there is an application on the Windows Phone Store called iWatch DVR that allows you to add a DVR system to watch its camera streams.
You can use the following link to install the software on your phone: https://www.microsoft.com/en-us/store/apps/iwatch-dvr/9nblggh09zxp
